Thanks for the welcome!
I have an R6 rear rim and run a 180 plus Penski shock and '04 R1 forks. Stock suspension wasn't great, like most bikes. Those mods are easy and I wouldn't hesitate if I had an FZ6.
I reason I ask about the FZ6 is years ago I had a 919 and turned down a ride on a 599...
Any riders compared the handling of the '06- present FZ-1 to FZ-6? I'm sure the Fz-6 is nimbler and I'm wondering if I'd like it. I own an '06 FZ-1 that I enjoy but its rather heavy steering.
